JSBSim is an object-oriented (C++), multi-platform, 6-DOF, Flight Dynamics Model (FDM). It can be run as a standalone, batch-mode flight simulator (no graphical displays), or integrated with FlightGear or other flight simulator.
The aircraft models included in this project and distribution do not include any proprietary, sensitive, or classified data. This should be rather obvious. All data is derived from textbooks, freely available technical reports, or other public data.
Likewise, no proprietary code is included. All code included within JSBSim has been developed on a volunteer basis using publicly available information, and is often directly linked to a particular textbook, for educational reference.

GLUI is a GLUT-based C++ user interface library which provides controls such as buttons, checkboxes, radio buttons, and spinners to OpenGL applications. It is window-system independent, using GLUT or FreeGLUT.

A fast, unobtrusive and modern cross-platform GUI toolkit. Agar fully exploits hardware acceleration where available, but also supports simple frame-buffer interfaces. Agar is stand-alone and easily portable to new platforms and graphics systems.

PyOSG is a python wrapper for the OpenSceneGraph. Version number corresponds to the version of OpenSceneGraph that PyOSG should work with (e.g. PyOSG 2.8 should work with OpenSceneGraph 2.8.x). Still in early stages, so email mday299 if any problems!

Pyzzle is a cross-platform game engine for creating large-scale, 2D Myst-like adventure games. The engine supports 2D panoramas, features an intuitive design mode, and allows users to download content from the internet. Pyzzle is written using Pygame.

osgJuggler is a library suite that makes developing computer graphics appications for virtual reality easier. osgJuggler is a framework that allows you to develop a scene with OpenSceneGraph and view it on any platform supported by VRJuggler.

Yet Another Homemade Game Engine (yahge) is what the name says a free open source 3D Game Engine geared towards development of 3D First Person Shooters. Major goals are to provide a Rapid Prototyping System for Game Ideas or to make Game Demos for Resume
